Seed-Sterilizing 'Terminator Technology' Sows Discord

摘要

Plant biotech researchers usually try to give plants a leg up on evolution, packing them with genes to fend off assaults from insects, extreme weather, and herbicides. But the latest innovation to emerge from plant gene labs does just the opposite: It ensures that these attributes won't be passed along to the next generation. Using a neat trick of genetic engineering, companies can now ensure that genetically modified plants produce sterile seeds—a feat that will keep farmers coming back for fresh seed year after year.
